To all whom it may concern:

Be it known'that we, CI-ninLns A. .OLSON 3 and CLAUDE H. Tooinss, both citizens of the United States, and both residing at Geneva, 1n the county of Kane and State of Illinois, have invented new and useful Improvements in jl v renches, of which the 'following'is a clear, full, concise, and e'Xact description, referencebeing had to 'theacco'm'paflymg drawing, forming apart of this specifica In the drawings, in which one embodiment of our invention is shown' Figure 1 1s a side elevation. of the 1mproved wrench showing'the partsin posit1on for use;

Fig. 2 is a side elevation of the wrench with' parts folded; I 1 i Fig, 3 is a section on the line 3-3 of Fig. 1; i

Fig. 4 is a section on the line Hot Fig.

3 showing the manner in which the holder is mounted on-the braceyand I Fig. 5 is an elevation showing part of the brace and holder. v I

Referring to the drawings in detail, the wrench shown comprises a brace by means of which the wrench can be operated, a pair 'oi gripping aws'11 for 'holdinga nut and the like, and a holder 12 for the' jaws 11 connected with the brace 10.

The brace 10 is provided with the usual handles or grips 13 and and with the U-shaped crank member 144 on whichthe grips are rotatably secured. The holder 12 has such a connection with the brace that it can be swung from the position shown in Fig. 1 to the position shown in Fig. 2, and the connection is such thatthe holderwiil be securely held in either of these two positions. To accomplish this the holder 12 has a square opening 15 in. one side to receive a head 16 secured on the lower arm of the brace. This head has a rounded portion 17 and a squared portion 18, these two portions being alternately movable into the opening 15.

WVhen the portion 17 lies within the opening 15 the holder 12 can be rotated about the lower arm of the brace 10 as an axis,

'for the jaw's'll'. provided'with a half round.bearingpalt 23 l but when the squared portion 1'8"lie's in the opening 1 5 the'holder is heltl'from rotation with respect to the brace. Aspring 19 located'within the holder '12 surrounds the lower arm of the brace, bears against the head 16 and'tends to normally -hold' 'the squared portion 18 of the head within'the opening 15. A pin'19 extends through the head 16 and limits the distance to which the spring 19 can force the portion 18zwithin the opening 15,by coming in contact with the inside of the holder '12." The holder 12 comprises a sheet metal tube -havings'lots 21 1n opposite sides-to receive andguide the ends of a pin 22 whichffol'nls a "pivot These jaws 11 are each toreceive the pin- 22:."A spring 24'is "located between the jaws'll which'holds "the jaws 11 normally apart as 'far, as the holder 12 will permit. Thelower endof each jaw is provided with a rectangular'recess 25 for sp'ect to thebrace'lOjagainst the pressure of the spring 19 untilthe squared portion 18' is out of the o1')ening;15.* The holder 12 is then rotatedaboutthe lower arm of the brace 10 to the position showninFig. 2

where it lies substantially between the up- Per -a:nd"lower armsotthe' braee. b it occupies very littl Having thus described our invention what 'we claim as newand desire'to s'ecure by"Letters Patent is j 1. In adevice of the class described a brace having upper and lower arms and a portion connecting said' arms"; gripping means, and a holderfor said'grippin means connected to sa1d-'br'ace,s'a1d holder having a non-circular opening'therein, and'a noncircular member fitting said opening and i non-rotatable with respect to said lower arm and movable into and out of said opening,

the connection being so constructed that the holder can be swung about said lower arm as an axis from a position substantially out side of the arms of the brace to a position substantially between said arms. 7

2. In a device of the class described a brace having upper and lower arms and a portion connecting said arms, gripping means, and a holder for said gripping means connected to said brace, said holder comprislower arm extends, one of said openings being non-circular, and a non-circular member fittmg said opening and non-rotatable with respect to said lower arm and movable into and out of said opening, the connection being so constructed that the holder can be swung about said .lower arm as an axis from a position substantially outside of the arms of the brace to a position substantially between said. arms.

3. In a device of the class described a brace having upper and lower arms and a portion connecting said arms, gripping means, and a holder for said gripping means connected to said brace, said holder comprising a tubular member. having openings in opposite sides thereof through which said lower arm extends, one of said open ings being non-circular, and a member fixedly secured with respect to said lower arm and slidable in said non-circular opening and having a first portion rotatable in said opening, and a second portion non-ro tatable in said opening, said portions being alternatively movable into said opening, the connection being so constructed that the holder can be swung about said lower arm as an axis from a position substantially outside of the arms of the brace to a position substantially between said arms.

4. In a device of the class described a.

brace having upper and lower arms and a portion connecting said arms, gripping means, and a holder for said gripping means connected to saidbrace, said holder comprising a tubular member having openingsa position substantially outside of the arms of the brace to a position substantially between said arms.

5. In a device of the class described a brace having upper and lower arms and a portion connecting said arms, 7 gripping means, and a holder for said gripping means connected to said brace, said holder comprising a tubular member having openings in opposite sides thereof through which said lower arm extends, one of said openings being non-circular, and a member fixed-1y secured with respect to said lower arm and slidable in said non-circular opening and having a first portion rotatable in said opening and a second portion non-rotatable in said opening, said portions being alternatively movable into said opening, and spring means tending to hold said second portion in said opening, said spring means including a coil spring within said tubular member surrounding said lower arm, the connection being so constructed that the holder can be swung about said lower arm as an axis from a position substantially out side of the arms of the brace to a position substantially between said arms.

6. In a device of the class described a brace having upper and lower arms and a portion connecting said arms, .gripping means, and a holder for said gripping means connected to said brace, said holder comprising a tubular member having openings in opposite sides thereof through which said lower arm extends, one of said openings being non circular, and a noncircular member fitting saidopening and non-rotatable with respect to said lower arm and movable into and out of said opening, said gripping means including a pair of jaws slidably mounted in said tubular -member, the connection being so constructed that the holder can be swung about said lower arm as an axis from a position substantially outside of the arms of the brace to a position substantially between said arms.

In witness whereof, we have hereunto subscribed our names.
